一种三维模型文件设计及其在光线跟踪中应用

摘要

The modern three-dimensional programsare capable of showing realistic and complex scenes, the needs of this area for the smart phone system become more and more insufficient. Nevertheless, the existing three-dimensional model file format is difficult to satisfy current and future requirements of a complex and large-scale three-dimensional application in smart phone. Presents a novel three-dimensional mod-el file format(zzd), this new file format has a reliable structure satisfy the requirements of the large-scale storage of complex models. It has good scalability, coupling, can efficiently read loads, and model compression and streaming. The file format and the application is experi-mented by using ray tracing algorithm on the Android platform. Experiments indicate that the file format can accommodate three-dimen-sional scene application requirements.%现代三维程序能够表现逼真复杂的场景，智能手机系统针对这方面的需求越来越明显，而现有三维模型文件格式难以满足目前及未来智能手机端更复杂的大规模三维程序的要求。给出一种新型的三维模型文件格式（zzd），这种新型文件格式具有可靠的结构，能够确保大规模复杂模型的存储，同时具备良好的可扩展性、耦合性，能够高效的读取载入，并进行模型压缩和流式传输。经采用光线跟踪算法对其在Android平台下进行实验应用。实验表明，该文件格式能够适应三维场景应用需求。
